- Place the Spinpro tip in the back side of Dong-A Com.ssa barrel.
- Place the SuperGrip grip on the 5 cm section of Dong-A Com.ssa (Striped side first )(it should cover the Spinpro tip).
- File the remaining visible part of Dong-A Com.ssa barrel (from the 5 cm section) until it fits snugly inside the front side of Factis barrels (the cut side). Assemble when ready. (if it's sanded too much, add teflon tape)
